The novel hydrocarbon polymers containing 6-membered rings directly connected in the main chain can be synthesized by living anionic polymerization of 1, 3-cyclohexadiene. Various types of 1, 3-cyclohexadiene-butadiene and 1, 3-cyclohexadiene-styrene block copolymers are also synthesized by living anionic polymerization of 1, 3-cyclo-hexadiene and butadiene or styrene. Completely hydrogenated poly (1, 3-cyclohexadiene) is composed of cyclohexane rings directly connected in the main chain, and has the highest glass transition temperature (Tg) among all hydrocarbon polymers. Completely hydrogenated 1, 3-cyclohexadiene-butadiene-1, 3-cyclohexadiene triblock copolymer is one of the best heat resistant hydrocarbon elastomers. These novel hydrocarbon polymers and block copolymers containing directly connected cyclohexene rings or cyclohexane rings in the main chain have high heat resistance and excellent mechanical properties for the new industrial materials.
